Abstract
The lip-type seal of the present invention includes a seal ring made of an elastic material so as to have an annular fitted part that is fitted to a housing and a lip part that extends from the fitted part inwardly in a radial direction in the shape of a substantially conical ring and that is brought into contact with a shaft, and a support ring including an annular joint part joined to the fitted part and an annular supporting part that defines a hole through which the shaft passes, that extends from a side of the joint part to a halfway area of the lip part, and that supports the lip part from inside in a radial direction. The lip part is tapered in cross section from an area from which non-contact with the supporting part starts toward an end thereof.
